Effect of coconut oil, milk powder on the viscosity and hardness of mixtures of cocoa powder and cocoa butter

The cutting and breaking hardness of mixtures (at 100C and 200C) decreased sharply when the cocoa butter content was more than 50% of the mixture by weight. The solidification temperature of mixtures decreased from 240C to 200C when the coconut oil ratio increased from 20% to 40% of mixture weight.
